详细

The data on the abundance and biomass of dreissenid underyearlings in macrophyte stands in different zones of the mouth part of a small tributary of Rybinsk Reservoir are presented. The highest density and biomass of underyearlings are recorded in the transient zone of the reservoir and the river mouth cross section. It is shown that the number of dreissenid underyearlings inhabiting the mouth area has not changed considerably in the years with unfavorable meteorological conditions.
